Robust statistics provide an alternative approach to classical statistical estimators

such as mean, standard deviation (SD), and percent coefficient of variation

(%CV). These alternative procedures are more resistant to the statistical

influences of outlying events in a sample population-hence the term "robust."

Real data sets often contain gross outliers, and it is impractical to systematically

attempt to remove all outliers by gating procedures or other rule sets.

The robust equivalent of the mean statistic is the median. The robust SD is

designated rSD and the percent robust CV is designated %rCV. For perfectly

normal distributions, classical and robust statistics give the same results.

Of course it is! If the mean of a set of data is negative, then the coefficient of variation will be negative.

Can you have a negative coefficient in a direct variation?

Yes, you can have a negative coefficient in a direct variation. So if you had y = -7x, that would be a direct variation. If you have y = -x, I do not know, if that is what you mean. Hope it helped.

How do you calculate coefficient of variation in spss?

The coefficient of variation is a method of measuring how spread out the values ​​in a data set are relative to the mean. It is calculated as follows: Coefficient of variation = Οƒ / ΞΌ Where: Οƒ = standard deviation of the data set ΞΌ = average of the data set If you want to know more about it, you can visit SilverLake Consulting which will help you calculate the coefficient of variation in spss.

Is it possible for a coefficient of variation of a set of data to be zero Explain.?

Yes it is. If all the observations have the same non-zero value then the coefficient of variation will be zero.
